JOHN O. RYIN, OF LEWISTOWN, ILLINOIS.

SHOCK-LOADER.

Specification of Letters Patent.

Patented Dec. 1, 1908.

Application filed August 7, 1908. Serial No. 447,458.

To all whom it may concern:

Be it known that I, JOHN O. RYIN, a citizen of the United States, residing at Lewistown, in the county of Fulton and State of Illinois, have invented certain new and useful Improvements in Shock-Loaders, of which the following is a specification.

This invention relates to hoisting and loading apparatus, and it has particular reference to that class of hoisting apparatus which is generally known by the designation of shock loaders, which is used. for the purpose of hoisting 0r elevating shocks of corn stalks or fodder and other heavy material from the ground and depositing the same upon a rack or in the box of a wagon,

for transportation.

The present invention has for its object to provide an apparatus of the class described which may be readily attached to and used in connection with a wagon of ordinary construction, said apparatus comprising a supporting truck and a hoisting derrick adapted to be conveniently operated by hand.

A further object of the invention is to so construct and arrange the hoisting derrick that the shock or other material, after being raised to the desired elevation, may be swung into position above the wagon box, and readily lowered or discharged into the latter, or upon a rack when a rack is used.

Further objects of the invention are to simplify and improve the construction and operation of this class of devices. I

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of arts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details herein exhibited, but that changes, alterations and modifications within the scope of the invention may be resorted to when desired.

In the drawings-Figure 1 is a perspec tive view of a shock loader constructed in accordance with the invention. Fig. 2 is a side elevation partly in section showing the upper portion of a hoisting derrick and of the braces supporting the same. Fig. 3 is a detail view in sectional elevation showing a portion of the derrick frame, the winding roller and a ratchet and brake-mechanism for the latter. Fig. 4 is a detail view in elevation taken approximately at right angles to Fig. 3. Fig. 5 is a sectional detail view taken through the lower portion of the derrick frame and showing the pivot of said frame.

Corresponding parts in the several figures are designated by like characters of reference.

The improved loading apparatus includes a supporting truck comprising an axle 5, having transporting wheels 6, 6, said axle supporting a pair of forwardly converging frame beams or sills 7,7, which are arranged in V-shape, and which are connected at their front ends by suitable means, such as a casting 8, which is constructed to form a clevis 9 adapted to be conveniently connected with the hind axle of a wagon or vehicle, as indicated indotted lines at 10, in Fig. l of the drawings. The sills 7 are connected intermediate their end by a crossbrace 11 and cross piece 12, the latter constituting a floor or platform in rear of and adjacent to the brace 11.

Rising from the rear ends of the sills 7, with which they are suitably connected, are forwardly and upwardly converging framebeams or uprights 13, occupying an inclined position as shown, and connected with the sills by means of inclined braces 14:, whereby they are strongly sustained and reinforced. Cross-braces 15 connect the rear sides of the uprights 13, said cross-braces extending diagonally across one another, thus affording an efficient and durable frame structure. The upper extremities of the uprights 13 are connected by a casting 16, which constitutes a cap and which is provided with a forwardly extending bracket 17.

The derrick frame D, which is triangular in shape, includes the side-bea1ns 18 and the base-beam 19, which are suitably connected together; upon the under side of the base beam 19 there is secured a wear-plate 20 and a corresponding plate 21 is secured upon the upper side of the cross-brace 11, said plates being connected by a bolt 22 which constitutes one of the pivots of the derrick frame; the opposed facesof the plates 20 and 21 may be provided with grooves or ball races 23, in which anti-frictional balls 24 may be placed, as shown in Fig. 5. The apex of the tending pintle 25, which is journaled in an aperture in the bracket 17, projecting from the cap 16, at the upper ends of the beams 13, said pintle being in axial alinement with the bolt 22, and thus forming a rotary sup: port for the upper extremity of the derrick frame. V i

The side beams 18 of the derrick frame are provided with boxes 26, affording bearings for a shaft 27, having at one end a crank 28, whereby it may be manipulated; said shaft carries a winding roller 29 and it is equipped with a ratchet wheel 30 and with a brake disk 31. The ratchet wheel 30 is engaged by a spring actuated pawl 32, which is pivoted upon the proximate frame beam 18, and likewise pivoted or fulcrumed upon said beam at 32*, is a hand-lever 33 with which is connected one end of a flexible brake strap 34, which extends partly around so as to be capable of peripherally engaging the brake disk 31, and the other end or extremity of which is suitably connected with the beam or upright 18 of the derrick frame.

The flexible brake strap 34 is connected with the hand lever 33 by means of a stud 33 projecting laterally from said lever, and lying in the path of one end of the spring actuated pawl 32, the opposite end of which latter is normally in engagement with the ratchet wheel 30; it will be seen that when the hand lever 33 is operated to disengage the pawl from the ratchet, it at the same time serves to tighten or set the flexible brake strap 34 upon the disk 31, thus checking rotation of said disk and of the winding roller with which it is connected.

The derrick arm 35 is pivotally mounted upon a rod or shaft 36, that extends between the side-beams of the derrick frame below and adjacent to the roller carrying shaft 27. Said derrick arm is provided at its free outer end with divergent brackets '37, connected by a cross-piece 38, and constituting a push frame whereby shocks of fodder may be pushed and upset so as to be more conveniently manipulated by the hoisting or loading apparatus. Connected with the push frame at the free end of the derrick arm is a flexible member, such as a chain 39 having a terminal hook 40, and adapted to be conveniently connected with the material that is to be hoisted; the flexible member being used, if so desired, to form a sling. Suitably connected with the derrick frame 35, adjacent to the outer end of said arm is a block or pulley 41 over which guided a flexible hoisting member such as a rope or cable 42, one end of which is securely attached to the derrick-frame adjacent to the upper end of said frame; the opposite end of the flexible "hoisting element is connected with the roller 29, upon which it is wound; said hoisting element being first guided over a guide pulley 43, which is suitably supported for rotation near the upper extremity of the derrick frame.

From the foregoing description taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. The improved loading apparatus may be conveniently connected with any ordinary transporting vehicle. The platform 12 affords a convenient support for the operator, who, while standing upon said platform, may manipulate the derrick frame to swing the derrick arm into position adjacent to the material that is to be lifted and loaded. By releasing the spring pawl 32 from the ratchetwheel 31, the roller 29 may be rotated to unwind the rope or cable 32, thus lowering the free end of the derrick arm until the material to be lifted may be conveniently connected therewith. The winding roller is now operated to wind the rope, thus raising the free end of the derrick arm and the load carried thereby to the proper elevation, after which, by manipulating the derrick frame, the load may be swung into position above the rack or wagon box, when, by

manipulating the hand-lever 33 the pawl may be disengaged from the ratchet and the brake strap at the same time set upon the brake disk, thus checking the rotation of the winding roller and governing the descent of the load, which latter, after being disposed in the desired location, may be disengaged from the derrick arm thus releasing the latter for a repetition of the operation.

It is obvious that the blocks forming part of the hoisting tackle may be multiplied when desired in order to enable exceptionally heavy loads to be handled with ease, changes, and modifications of this character being regarded as entirely within the scope of the invention.

The improved hoisting apparatus will be found useful and serviceable not only for loading shocks, but for loadin and manipulating stumps, building material and, in fact, heavy materials of all kinds. The apparatus may also be used detached from a wagon, and numerous profitable ways for using a device of this character will readily suggest themselves.
